(Summary description)       What are the PTFE membranes activated by ptfe membrane plasma equipment? How is the process? Three surface treatment methods to improve the adhesion of PTFE membranes have different characteristics and treatment effects. Today, we will focus on the activation treatment in the ptfe membrane plasma equipment. The activation treatment of ptfe membrane plasma equipment can improve the adhesion of the PTFE membrane material surface. Which membranes can be treated with plasma equipment? So what is the whole activation process? Let us understand together.        Due to different applications and different material compositions, PTFE membranes can be divided into many different types, and which PTFE membranes can be processed by plasma equipment, this can also be said to be quite a lot, not to list them one by one, the following is PTFE Several typical materials of the membrane have been processed. , 1. PTFE film with red pigment and glass fiber added; 2. PTFE film with graphite or carbon powder added; 3. The addition of ceramic powder PTFE film. ,     Since the above PTFE membrane is the addition or compounding of other materials, it is necessary to adjust the corresponding process parameters during the activation process of the specific ptfe membrane plasma equipment. Therefore, different PTFE membranes and different treatment purposes often correspond to different process parameters, and the plasma surface treatment process has a certain flow. Let's take a certain proportion of ceramic powder into the PTFE membrane as an example to introduce to you.           The purpose of plasma surface activation of ptfe membrane plasma equipment is to process the epoxy resin and PTFE membrane before pressing, and improve the adhesion with epoxy resin. Plasma surface activation process: Put the treated PTFE membrane into the vacuum chamber of the vacuum plasma surface treatment equipment, close the door and evacuate to 20-50Pa, and pass in a certain amount of process gas to maintain a certain degree of vacuum Perform plasma discharge, set the power and processing time, and then return the gas to break after the processing is completed, then open the door of the processed PTFEP tetrafluoroethylene membrane, and take out the processed PTFEP tetrafluoroethylene membrane.        In the detection of plasma activation effect, it can be reflected by changing the angle of the contact angle of water droplets. In addition, after 1000 hours of ultraviolet light aging test, the tensile value of the treated PTFE film reached 9N/cm or more, but the UV light aging test still did not peel off, the tensile value did not change much within the specified range, after the ptfe film plasma equipment plasma After surface activation, the bonding effect is qualified.
